Marine Corp. Prints Stainless-Steel Headcap for Mine-Clearing Device

September 15, 2021

Continuing its quest to leverage additive manufacturing (AM) for battlefield prowess, the U.S. Marine Corps reports success in metal AM of a component for a mine-clearing device. The Program Manager for Ammunition (PM Ammo) at Marine Corps Systems Command (MCSC) 3D printed a headcap for a rocket motor used to detonate a M58 Mine Clearing Line Charge (MICLIC), a rocket-projected explosive line charge that provides a demining capability for Marines.

“The previous process of traditional manufacturing is outdated, while 3D printing is a more modern manufacturing technique,” says PM Ammo engineer Caleb Hughes. “I truly believe that 3D printing is the next generation of the Marine Corps.”

Predicting AM-Part Performance

Post-processing steps such as heat treatment, hot isostatic pressing and surface finishing, though not as compelling as building a part one layer at a time, significantly affect AM-part performance. Recognizing the importance of post-processing, we’ll describe a probabilistic model developed by EWI to predict part performance based on both the build process and the post-processing technique.

The Challenges of 3D Printing Superalloys
Aviation, aerospace and heavy industries have begun looking at AM of superalloys as potential game-changing technology. AM can deliver complex, previously unmanufacturable, innovative designs that boost product performance while reducing supply-chain delays and associated production costs.
